The Diagnostic Dilemma of Ruptured Liver Metastasis in a Patient with Lung Cancer: A case report.

Spontaneous rupture of a metastatic liver tumour is rarely documented in the literature when compared to hepatocellular carcinoma and other liver lesions, especially from a lung primary. We report a case of ruptured liver metastasis from an adenocarcinoma of the lung mimicking ruptured liver abscess, challenging the clinical diagnosis. A 42-year-female patient presented to a tertiary care institute in 2020 with complaints of abdominal pain, breathlessness and fever. On examination, the patient was tachypnoeic with a right hypochondriac mass. A contrast-enhanced computed tomography of abdomen and thorax revealed an ill-defined heterogeneously enhancing lesion in the liver with a communicating subcapsular collection and hypo-enhancing lesions in the left lobe and heterogeneously enhancing lesion in the left lung. Adenocarcinoma of the lung with hepatic metastasis was confirmed with a core needle biopsy. The patient was managed conservatively with intravenous antibiotics, intercostal drainage tube and gefitinib. However, despite best efforts, the patient succumbed to the disease.
